Description

Technical Field

[0001] The utility model relates to a laboratory verification system for ultrasonic industrial applications, belonging to the field of ultrasonic technology. Background Art

[0002] Industrial solid wastes such as tailings, slag and sludge contain a large number of metal elements. Generally, the wet metallurgy leaching method is used to extract valuable metal elements from industrial solid wastes. However, the conventional leaching process is usually restricted by slow mass transfer, momentum transfer, heat transfer and chemical reaction processes. Ultrasonic-assisted leaching is an effective method for extracting valuable metals from different types of industrial solid wastes by using mechanical or chemical mechanisms such as bubble cavitation. The cavitation effect and mechanical effect generated by ultrasonic equipment can form effective turbulent disturbances in the solution, accelerate the material diffusion and dissolution process, generate strong microjets on the surface of mineral particles, reduce the surface tension and internal friction of the solution, and destroy the solid-liquid interface state, thereby significantly increasing the metal extraction rate from solid wastes.

[0003] However, in the process of popularizing and applying existing ultrasonic leaching equipment from laboratory scale to industrial scale, the results obtained in the laboratory are difficult to be quickly scaled up to industrial scale because the ultrasonic output power in the laboratory cannot be fully utilized or the power density cannot be accurately adjusted. In addition, the wet metallurgy leaching process is usually in a strong acid or strong base environment, and the ultrasonic equipment needs to be inserted into the solution to work continuously, so its continuous use faces harsh conditions. Therefore, it is necessary to develop a laboratory verification system for ultrasonic industrial applications to solve the problem of quickly scaling up laboratory research results to the industrial application field. Summary of the Utility Model

The system includes an ultrasonic transmitting device, an ultrasonic reaction device, a mechanical stirring device and a real ultrasonic power monitoring device; a protection device is arranged outside the ultrasonic transmitting device. The real ultrasonic power monitoring device monitors the real ultrasonic power of the liquid-phase solution in the ultrasonic reaction device, and the ultrasonic loss coefficient can be calculated according to the real ultrasonic power of the liquid-phase reaction solution and the ultrasonic output power. Based on the ultrasonic loss coefficient, the optimized laboratory parameters can be quickly scaled up to industrial levels in proportion. The laboratory verification system can solve the problem of expanding existing ultrasonic equipment from laboratory scale to industrial scale and eliminate the bottleneck that the output power of laboratory ultrasonic equipment cannot be scaled up to industrial scale in proportion.
